wood shavings absorb nitrogen during decomposition so their use can cause nitrogen deficiency, coco coir decomposes very slowly and proved to improve soil's water holding capacity and softens the planting media structure ...

The germination rate was good 7 out of 11 seeds have been germinated so for, coco coir plays an important role as it holds up the moisture for a longer time compared to soil thus enabling the use of less water and as it is very light in weight the seeds can easily sprout without utilizing much of their limited energy to break through the surface...
